That figure looks like an origin-destination analysis. Here is the relevant ArcGIS Pro online documentation: https://pro.arcgis.com/en/pro-app/3.1/tool-reference/analysis/generate-origin-destination-links.htm Good luck!
Michael Gilbrook That's what it looks like to me, also. The nodes are at the centroids of the village polygons, not intersections, and the lines pass across intermediate polygons.
